You are a blessing for every medical student. Love and respect you from the core of my heart. I dont know how to express what I am feeling right now. Just.. Be billionaire and stay in good health.

I would never get this information from my university, you made everything crystal clear THANK you so much ..

[eugenmweemba]

Just wow😮 Five(5) years later and still unmatched Crystal clear concepts 🙏

You are a life saver... we have an Anatomy teacher that basically disappeared and abandoned her students and I have been able to provide them content through your videos. THEY LOVE YOU! Thank you!/

I love this video, and I am excited to watch the rest of the cranial nerves - which I know far less about. I've been working in an ENT department for about 1.5 years now, so I wanted to add a few things. First: anosmia is complete loss of smell, hyposmia is reduced smell. Usually, during a cold, you have hyposmia.

The most common causes in order of anosmia are as followes:
1) Post-viral injury/damage
2) Trauma breaking the nerves
3) Chronic inflammation, like from allergies, covering the olfactory nerve
4) Far less common, tumors or masses.

Also, one thing awesome, if the nerve is damaged from trauma or an infection, the olfactory nerve is the only cranial nerve that can grow back, so the doctors I work with are know recommending olfactory retraining, sort of like PT for the nose. It has worked pretty well.

I am neurology resident and you are my official reference for neuroanatomy, this is unbelievable you are a legend

[hermie]

wow, my university made us just remember the lesions from 5-8 blindly without any explanation. You have made everything clear, cannot thank you enough! 🙏🏻, please keep up this channel! 👌🏻

[crazypiper]

This is excellent work mate! Keep it up!

[rohitroll]

Every single video of yours is awesome.. First year med student here..and for me you're nothing less than a blessing..

[quaro]

I literally cheered because i finally understood how the various lesions impacted on vision. maybe you saved my ophtalmology exam next month!

[linayas]

trust me ive watched several videos about visual pathway and lesions but yours is the best i couldn't understand till i watched yours THANK YOU SO MUCH you are saving a lot of peolple here ! God bless you

[sketchwithmich]

I'm an international student in Germany, majoring in biology (well not a medical student). German is not my first language and i feel like I always need more time to understand what was taught in the lecture than other fellow students who are germans. I'm currently taking Physiology as a module this semester and I just can't stress it enough..how grateful I am to have found your channel 🥲thank you so much!!

[Colton-Hoerner]

Your the man! Better than my professor for anatomy by a long shot!

[mb]

holly hell.. i cant believe i actually followed through the whole thing .. lol ..ur a gem. THANKYOU

[ernestssewanyana]

You're doing a great job Zac. 30 minutes and optic tract is clear. Can't thank you enough. Be blessed sir!

[rawan]

There are not enough words to describe how much i appreciate your efforts. THANK YOU

[pkalamaris]

Sam Webster was number one until I watched your videos my friend. The detail into which you go is awesome! Kudos!

[snarminoxx]

I'm blown away by your ability to unpack and communicate such a potentially intractable subject (bad pun). Your choices of when to use "Nasal/temporal" vs "L/R" were astute, and kept left/right confusion to an absolute minimum. You have helped a lot of people with these videos. THANKS!

[chamindakumara]

I always double-check my lessons about Optometry with your channel. Thank you so much from Sri Lanka
